RockJock JL/JK Johnny Joint Billet Aluminum Control Arms Rear Lower Adjustable Pair

When you're lifting your Jeep Wrangler JK or JL, you'll often need to adjust the pinion angle to get everything aligned correctly. This pair of rear lower adjustable control arms from RockJock is designed to help you do just that. You get a pair of CNC machined billet 6061-T6 aluminum control arms, each fitted with RockJock's well-known Johnny Joint rod ends on both ends. These joints allow for the necessary movement and flex your suspension needs, while the arms themselves are double-adjustable thanks to right-hand and left-hand threads. This adjustability is key for dialing in your pinion angle after a suspension lift.

Beyond the adjustability, these arms are built tough. The billet aluminum construction is finished with black anodizing and machined highlights, giving your Jeep a sharp look. For added protection, they include bolt-on 4130 chromoly skid plates that can be replaced if they get damaged. These arms are a direct replacement for your stock lower control arms and are designed to work with 37-inch tires on stock-width axles with a 4 1/2-inch backspace wheel. Keep in mind that if you plan to run larger tires, you might need wider axles or wheel spacers. It's also important to note that these adjustable lower arms must be used in conjunction with adjustable upper control arms for proper setup.
